8400M (MXM Card)

Hi,

I've got a newly installed OSX Lion system on an all-in-one desktop computer.

It has an nVidia 8400M GS card inside, this is an MXM card (like a miniature PCI card). It also has DVI-out.

Problem is, if I use Graphics Enabler / NVEnabler, the display seems to output to the external DVI port, not the internal LCD screen. All I get is a 'black screen'.

 

I do not currently have a DSDT file.

Does anybody know if creating and editing a DSDT would enable the nVidia card to select the proper output channel?

Thanks,

Hi, you can always extract your raw DSDT from BIOS and post it so that we have a look. Also add your saved IOReg outout using IORegistryExplorer. May be a simple injection of nVidia info will sort things out. No harm in trying...
